“Another family member was angered that I might attend, and I was told she was just not willing to forgive me yet. She wouldn’t forgive me! For abuses perpetrated against me as a child, or for exposing those abuses perhaps,” she wrote via People.

In her first book, “High on Arrival,” which was published in 2009, Mackenzie, 57, detailed how she was raped at 19 by her father John Phillips of the Mamas and the Papas while both were under the influence of substances. They later began a nearly 10-year relationship.

While some members of the family have questioned the validity of her claims, Mackenzie has found support elsewhere.

“I’ve come to understand that some in my family have chosen to hold on to the pain and anger they felt when I came out with the truth about my dad. I understand that they’re still caught in a textbook response of devaluing the victim and holding up the perpetrator,” she shared.

Mackenzie continues to move forward with her life. A former drug addict, she is now a drug counselor at the Breathe Life Healing Center in Los Angeles.

“I’ve also had to accept that, of course, I’d be the target of negative reactions and feelings because I’m the one who wrote the book and told a truth no one wanted to hear. If you’re trying to maintain some sort of façade so you can avoid pain, the last thing you want is for the façade to be demolished.”
